ADDIS ABABA/NAIROBI (Reuters) – Ethiopia resisted international pressure for mediation in a war in the country’s north on Monday as its air force bombed the Tigrayan capital Mekelle, according to diplomatic and military sources.

Hundreds have died, 25,000 refugees have fled to Sudan and there have been reports of atrocities since Prime Minister Abiy Ahmed ordered air strikes and a ground offensive on Nov. 4 against Tigray’s local rulers for defying his authority.
